Triploid Grass Carp are hatchery-raised, sterile fish used in some ponds and lakes as part of aquatic vegetation management programs.
Appearance
Long, torpedo-shaped carp body with large scales and a broad, blunt head.
Typical Size
They can become large fish and may live for many years under suitable conditions.
Habitat
Ponds and lakes where aquatic vegetation is present and where stocking is legally permitted and biologically appropriate.
Diet
Primarily aquatic vegetation, though plant preference and control effectiveness vary by plant species and conditions.
Role in a Pond or Lake
Used as a biological vegetation-management option that may complement other control methods.
Spawning & Reproduction
Triploid fish have three sets of chromosomes and are sterile, so they are unable to reproduce normally.
